If I have a midi part, that I just have recorded, and the cursor is outside the part boundaries the Key Editor will open, so the start of the part is visible, not necessarily showing the data closest to the cursor. If the cursor is inside the part boundaries the Key Editor will open “correctly” and show the events near/under the cursor.
Wouldn’t it be lovely to force Cubase always to open the Key Editor so the events near/under the cursor are in focus.
And I know ALL the fast ways of getting the editor to show what I want, but I try to minimize the numbers of clicks.
Could you make a couple of screenshots to show what you are doing? Maybe also let us know the settings in the Key Editor regarding part display.
